We have discussed this before - there is always nasty compromise when it
comes to example vs default. Good for one is often not good for the
other. But like it or not, our example pretty much is the defacto
default as you say.

As a reminder, in the past we have talked about doing both an example
with all the bells and whistles, and a performance config that you
should really start from. But we have not gotten there obviously ;) Adds
some dev/maint overhead as well.

No real points, just chiming in with that.
